Abstract
Alat penukar panas (heat exchanger) memiliki perananan penting di dalam industri. Peningkatan performa dari heat exchanger diperlukan untuk mendapatkan hasil laju perpindahan panas yang maksimal. Selama ini telah banyak upaya yang telah dilakukan untuk peningkatkan performa dari heat exchanger salah satunya dengan memvariasikan baffle yang terdapat di dalam heat exchanger. Pada penelitian ini dilakukan variasi pada ¬baffle bertipe segmental dengan kemiringan 0, 10, dan 20 dan disertai penambahan finned tubes bertipe longitudinal sebanyak dua buah fins tiap tube nya dengan menggunakan metode Computational Fluid Dynamic (CFD). Hasil simulasi menunjukkan bahwa penambahan fins tiap tube berpengaruh terhadap besarnya area perpindahan panas dimana akan membuat performansi laju perpindahan panas dapat meningkat sedangkan kemiringan segmental baffle akan menyebabkan menurunnya pressure drop. Laju perpindahan panas tertinggi didapatkan oleh variasi heat exchanger segmental baffle 10 dengan fins pada setiap tube dengan nilai yakni yakni 423.604,162 Watt dan untuk pressure drop paling rendah didapatkan oleh variasi heat exchanger segmental baffle 200 tanpa penambahan fins pada setiap tube dengan nilai 899,15 Pa.

Heat exchangers have an important role in the industry. Improved performance of the heat exchanger is needed to get the maximum heat transfer rate. So far, many efforts have been made to improve the performance of the heat exchanger, one of them is by varying the baffles contained in the heat exchanger. In this study, variations were made on segmental type affles with slopes of 0, 10, and 20 and accompanied by the addition of longitudinal type finned tubes of two fins per tube using the Computational Fluid Dynamic (CFD) method. The simulation results show that the addition of fins per tube affects the amount of heat transfer area which will make the performance of the heat transfer rate can increase while the slope of the segmental baffle will cause a decrease in pressure drop. The highest heat transfer rate is obtained by varying segmental baffle heat exchanger 10 with fins in each tube with a value of 423.604,162 Watt and for the lowest pressure drop obtained by segmental baffle 20 heat exchanger variation without adding fins to each tube with a value of 899,15 Pa.
